Marine algae have been recognized as a rich resource of new
and unusual organic molecules with diverse biological properties.
The current need to develop new antifungal, anticancer, antibiotic
and antiviral drugs has led to an intense research effort into the
discovery, isolation and structure determination of potential
medicinal agents from...
Characterization of the 5' flanking region of rainbow trout ki-ras gene was begun with the cloning and sequencing of this region by the inverse PCR technique and dideoxynucleotide chain termination method. In total, a nucleotide sequence of 1080 bp upstream from the first coding ATG was sequenced. Although this region...
Some parasites may modify the behavior of their
hosts. Altered behaviors may: 1) benefit the host in
that they defend against the pathogen, 2) benefit the
pathogen and represent manipulations of the host
response, and 3) benefit neither the host or the
pathogen and simply be a product of the...
There is plenty of evidence from epidemiology studies
supporting a link between certain components in the human
diet and cancer incidence. It is estimated that 3-4 million
annual cases of cancer could be prevented worldwide just by
changing dietary habits. In parts of the world where
vegetables and fruits constitute...
Identifying appropriate units for conservation requires knowledge of evolutionary
patterns and risks of managing at different geographical and genetic scales. I examined
genetic diversity at different geographical scales among 11,400 rainbow trout
(Oncorhynchus mykiss) from 243 locations in 13 major river basins throughout much of
their range and among coho...
Populations of coastal cutthroat trout, Oncorhynchus clarki clarki, were sampled in 16 headwater streams from logged (20-30 and 40-60 years ago) and unlogged (stand age 125-150 years) basins. Basins logged 20-30 years ago supported the widest range of mean biomass of age 1+ or older cutthroat trout (g/m2) and the...
By using immobilized trypsin, I have been able to
prepare well-defined, stable trypsinized nucleosomes. The
difficulties of lacking of control in the extent of
trypsinization, which were encountered in previous studies
with the use of free trypsin, have been eliminated. The
nucleosomes and oligonucleosomes prepared by immobilized
trypsin are suitable...
